Description

Technical Field

[0001] The utility model relates to the technical field of Roots blowers, in particular to a large-flux Roots blower parallel mechanism. Background Art

[0002] The high-throughput Roots blower parallel mechanism is a device that combines multiple Roots blowers and realizes parallel operation through a specific connection method to achieve the purpose of high-throughput gas transportation. The Roots blower itself is a volumetric gas compression machine. Its working principle is based on the rotational motion of two intermeshing rotors in the casing, continuously transporting gas from the air inlet to the air outlet.

[0003] After searching, the patent with announcement number CN213655123U discloses a large air volume Roots blower parallel unit. Although the large air volume Roots blower parallel unit drives two ordinary Roots blowers through one motor to avoid setting up too many power sources, it increases the load of a single motor, causing the transmission mechanism to overheat easily during operation, affecting the operating efficiency and service life.

[0004] In response to the above problems, this utility model document proposes a large-flux Roots blower parallel mechanism. Utility Model Content

[0005] The utility model provides a large-flow Roots blower parallel mechanism, which solves the shortcomings of the prior art that although a large-flow Roots blower parallel unit drives two ordinary Roots blowers through one motor, thus avoiding the need to set up too many power sources, the load of a single motor is increased, resulting in the transmission mechanism being easily overheated during operation, thereby affecting the operating efficiency and service life.

[0006] The utility model provides the following technical solutions:

[0007] A large-flux Roots blower parallel mechanism, comprising:

[0008] A U-shaped base frame, wherein two Roots blower bodies are symmetrically fixedly mounted on the inner wall of the U-shaped base frame, and the two impellers meshing in the Roots blower bodies are synchronously rotated by two first gears meshing on the outer wall thereof, wherein a common transmission rod is fixedly disposed between the two opposing first gears;

[0009] The synchronous drive assembly is provided on the transmission rod and is used to synchronously drive the two Roots blower bodies to operate;

[0010] The self-heating component is installed in the U-shaped base frame to reduce the operating temperature of the entire structure to ensure operating efficiency and service life.

[0011] In one possible design, the synchronous drive assembly includes a second gear fixedly provided on the transmission rod, a drive motor is fixedly mounted on the outer wall of the U-shaped base frame, the output shaft of the drive motor passes through the inner wall of the U-shaped base frame and is fixedly provided with another second gear, and the two second gears are engaged with each other.

[0012] In one possible design, the self-heating component includes a cooling fan fixed to the bottom of the inner wall of the U-shaped base frame through connecting rods at the four corners of the bottom, a second bevel gear is fixed on the rotating shaft of the cooling fan, and a first bevel gear is fixed on the transmission rod, and the first bevel gear and the second bevel gear are engaged with each other.

[0013] In a possible design, the input ends of the two Roots blower bodies are connected via an air inlet connecting three-way elbow.

[0014] In a possible design, the output ends of the two Roots blower bodies are connected via an air outlet connecting three-way elbow.

[0015] In a possible design, a connecting flange with an embedded sealing ring is fixedly provided at the access port of the air inlet connecting three-way elbow pipe and the air outlet connecting three-way elbow pipe.

[0016] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] When in use, first ensure that the large-flow Roots blower parallel mechanism has been correctly installed and powered on. After starting the drive motor, the output shaft of the drive motor begins to rotate, and drives the second gear fixed thereon to rotate. Since the two second gears are meshed with each other, when the second gear of the drive motor rotates, the second gear on the transmission rod will also rotate synchronously, thereby driving the transmission rod to rotate. The rotation of the transmission rod will drive the two meshed impellers in the Roots blower body to rotate synchronously, starting the gas compression and transportation process. The gas enters the input end of the two Roots blower bodies through the three-way elbow connected to the air inlet. In the Roots blower body, the rotation of the two impellers compresses the gas and pushes it to the output end. The compressed gas is combined through the three-way elbow connected to the air outlet and transported to the target location.

[0019] While the Roots blower body is running, the first bevel gear on the transmission rod will drive the second bevel gear on the rotating shaft of the cooling fan to rotate. The rotation of the cooling fan generates airflow to dissipate heat from the entire structure within the U-shaped base frame and reduce the operating temperature.

[0020] The utility model has the following beneficial effects:

[0021] The synchronous drive component in the utility model ensures the synchronous operation of the two Roots blower bodies, thereby improving the stability and reliability of the system; the self-heating component drives the heat dissipation fan to rotate by utilizing the rotation of the transmission rod, thereby achieving heat dissipation protection for the overall structure, reducing the operating temperature and extending the service life.

[0022] The entire large-flux Roots blower parallel mechanism of the utility model has a compact structure, and the components are tightly connected, which is easy to disassemble and repair, thereby reducing maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components. Example

[0031] Please refer to Figure 1-4 A large-flux Roots blower parallel mechanism, which is used in the field of Roots blowers, mainly includes a U-shaped base frame 1, two Roots blower bodies 2, a synchronous drive component and a self-heating component:

[0032] The U-shaped base frame 1 serves as the supporting structure of the entire parallel mechanism. It is rationally designed and can stably fix the two Roots blower bodies 2. Two mounting positions are symmetrically provided on the inner wall of the U-shaped base frame 1 for fixing the Roots blower bodies 2. The two Roots blower bodies 2 are respectively mounted at two symmetrical positions of the U-shaped base frame 1. Two impellers 3 are meshed in each Roots blower body 2. The two impellers 3 are synchronously rotated by two first gears 4 meshed on the outer walls thereof. In addition, a transmission rod 7 is fixedly provided between the two opposing first gears 4 for transmitting power and achieving synchronous rotation.

[0033] The input ends of the two Roots blower bodies 2 are connected through the air inlet connecting three-way elbow 5. This arrangement ensures that the two Roots blower bodies 2 can receive gas input at the same time. The output ends of the two Roots blower bodies 2 are connected through the air outlet connecting three-way elbow 6. This arrangement ensures that the gas output by the two Roots blower bodies 2 can be combined and transported to the target location.

[0034] The synchronous drive assembly includes a second gear 8, a drive motor 9 and another second gear 8 arranged on the transmission rod 7. One second gear 8 is fixedly set on the transmission rod 7, and the other second gear 8 is fixedly set on the output shaft of the drive motor 9. The two second gears 8 are meshed with each other. The drive motor 9 is fixedly mounted on the outer wall of the U-shaped base 1, and its output shaft passes through the inner wall of the U-shaped base 1 and is fixedly connected to the second gear 8. The drive motor 9 is responsible for providing power to drive the entire parallel mechanism to operate. When the drive motor 9 is started, its output shaft will drive a second gear 8 to rotate, and then drive the other second gear 8 and the transmission rod 7 to rotate through the meshing relationship.

[0035] The self-heating assembly includes a heat dissipation fan 10, a first bevel gear 11 and a second bevel gear 12. The heat dissipation fan 10 is fixed to the bottom of the inner wall of the U-shaped base frame 1 through connecting rods at the four corners of the bottom. When the heat dissipation fan 10 rotates, airflow is generated to reduce the operating temperature of the parallel mechanism. The first bevel gear 11 is fixed on the transmission rod 7, and the second bevel gear 12 is fixed on the rotating shaft of the heat dissipation fan 10. The two bevel gears are engaged with each other. When the transmission rod 7 rotates, it drives the first bevel gear 11 to rotate, and then drives the second bevel gear 12 and the heat dissipation fan 10 to rotate through the meshing relationship.
